===========================================================

We can't tell what you have done -- you can check.

What?

What you do, what you did, and what you install is at least partly determined by the Operating System / version you are running on your device (computer, tablet, phone).

-------------------------------------------------------------

Scanning from the printer is also different from scanning using an app or software program on your device.

For example, If you are trying to "Scan to Computer" from the printer control panel, you do have to have the Full Feature Software installed on your computer.

-------------------------------------------------------------

Relevant to Windows

"download the HP Software" might indicate you are running some kind of scanner app or software in (for example) Windows.

There are a couple of main apps and software options in Windows for scanning and several more options (not discussed here).

• HP Smart application for Windows
• Full Feature Software / full driver printer software
